I wished this looked more sober and sophisticated so that I could carry it anywhere. But hey its not the toy looks they are pitching but its function. And as the name goes, just fill this with water and a chemical reaction takes place to power up this device which can work for a month before the next refill.
Fancy one? Then order it here for $20.

水能计算机
我希望这东西可以看起来更加的朴素并且尖端，这样我就可以把它带到任何地方去。嘿，但这并不是一个如它看上去那么随处可见的玩具，它是个有实际功能的机器。就像它的名字所说的，只要把它放到水里面去，一种化学反应就会发生，产生能量提供给这个设备，而这些能量可以让它在下次冲能之前维持一个月的工作时间。
